Hmm, maybe my base vibration in my headphones eliminates that effect. :/

Edit: After watching the sixth video (I found on YouTube) it cause me to have a weird rushing sound in my earphones, even after I had taken them off. Like when you cup your hands over your ears, and all you hear is your blood rushing. Its weird. It then suddenly, without fading away, stopped. The sound just stopped instantly.
Edit2: I dont know about you guys, but after watching one of the video's, when I look away, my vision shakes. As if there is a miniture earthquake or something. But extremely subtle shakes. Like tiny vibrations in my vision.
